Karndean Flooring FAQ: Answers from a Buyer Who’s Been Through It

What I’ve Learned Ordering Flooring for Our Offices

I’m an office administrator for a 180-person company. I manage all our facility and maintenance ordering—roughly $50,000 annually across 12 vendors. I report to both operations and finance. Flooring replacements come up every couple of years when we reconfigure spaces, and Karndean has been a recurring name. Here’s what I’ve figured out, question by question.

What is Karndean flooring made of?

Karndean is a luxury vinyl tile (LVT) or luxury vinyl plank (LVP) product. It’s multiple layers: a clear wear layer on top, a printed PVC layer with the stone or wood design, a vinyl core, and a fiberglass layer for dimensional stability. I’m not a materials scientist, so I can’t speak to the exact chemical formulation. What I can tell you from a procurement perspective is that the construction matters for durability—specifically, the wear layer thickness (usually rated in mils) determines how long it holds up under chair wheels and foot traffic.

How much does Karndean cost? (Van Gogh pricing, specifically)

Pricing varies a ton by collection. The Van Gogh series is their premium line. As of January 2025, I’ve seen it quoted between $5.50 and $7.50 per square foot material only, depending on the distributor and volume. That’s just the product—installation, underlayment, adhesive, and trim all add up. A ballpark for a fully installed Van Gogh floor? I’ve paid about $10–$13 per square foot total for recent projects (circa 2024). Verify current pricing at local distributors; rates change quarterly.

Is Karndean the same as peel and stick?

No. Karndean’s core products are glue-down or click-lock (Korlok, Looselay). They don’t market traditional peel-and-stick tiles. If you’re looking for actual Karndean, you’re not buying a peel-and-stick product. I learned this the hard way when a vendor tried to upsell me on a “Karndean-comparable” peel-and-stick. It wasn’t the same thing. (Note to self: always verify the product line by name.)

Does Karndean work with radiant floor heating?

Yes, but with conditions. Their technical specs say the floor surface temperature shouldn’t exceed 80°F (27°C). I checked with their customer support before specifying it for a renovated break room with in-floor heating. They confirmed the adhesive systems are rated for it, but the heating system needs a gradual warm-up—don’t crank it on full after installation. This gets into engineering territory, which isn’t my expertise. I’d recommend consulting a flooring installer who’s done heated floors with LVT before.

How about soundproofing? Do I need soundproofing panels with Karndean?

Karndean itself doesn’t block sound—it has a hard surface. If you’re installing it in an upper-floor office or a multi-tenant building, you’ll want an acoustic underlayment specifically designed for floating floors. Regular soundproofing panels on walls are a separate product—they treat room echo, not impact noise from footsteps. For our second-floor meeting rooms, we used a fiberglass pad under the click-lock planks. That cut the transmitted noise noticeably. I’m not an acoustician, but pairing a proper underlayment with the flooring is standard practice.

Can I install Karndean over existing tile?

Sometimes. If the existing tile is flat, well-adhered, and clean—yes, you can glue down Karndean over it. If the tile is loose or uneven, you’ll need to level it or remove it. We tried this once over old ceramic tile in a break room (this was back in 2023). The installer flagged that the grout lines created slight dips. We ended up using a self-leveling compound before installation. Skipped the leveling step on a test patch and thought “what are the odds?” Well, the odds caught up—we saw lipping within six months. $400 fix.

How do I clean and maintain Karndean flooring?

The manufacturer recommends a neutral pH cleaner (they sell their own floor care kit) and microfiber mopping. No wax, no steam mops. I said “mop with mild soap” once. A distributor corrected me: “mild” doesn’t mean neutral. Their technical specs explicitly say to avoid vinegar and ammonia-based products. We had to strip and re-coat a hallway that got mopped with the wrong solution (circa 2022). That wasn’t cheap. So: read the care sheet.

What’s the warranty situation?

Residential warranties on Van Gogh are lifetime prorated. Commercial is shorter (5–10 years depending on collection). I’m not a legal expert, so I can’t speak to the fine print on what voids coverage. What I can tell you from a procurement perspective is: always register the warranty immediately after purchase. We missed a deadline on a 2021 install and lost coverage. The vendor’s responsiveness dropped after the first order (note to self: monitor this).

One more thing: hidden costs to watch for

I’ve learned to ask “what’s NOT included” before “what’s the price.” Shipping, delivery to upper floors, removal of old flooring, and disposal fees have surprised me more than once. The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end. I knew I should get a written quote with all line items. That’s saved me from “that’s extra” conversations more than once. The lowest quoted price often isn’t the lowest total cost.
